Kirsten Prout is going vamp for Eclipse.
The 19-year-old Vancouver native will star as vampire Lucy in the highly anticipated third installment of the Twilight series, her rep confirmed to E! News.
Lucy is a prominent part of Jasper's backstory and builds a bloodsucking army with Catalina Sandino Moreno's Maria. Maria and the newest Cullen will eventually kill her.
Prout, who cut her teeth as Jennifer Garner's protégé in Elektra but is best known for her role as literal girl-next-door Amanda on ABC Family's Kyle XY, will join scream-inducing hotties Robert Pattinson, Kristen Stewart and Taylor Lautner on the locked-down Eclipse set.
